Rechargeable USB Batteries
Rechargeable USB batteries are made to combine the convenience and innovation that serve a sustainable power source solution with built-in USB charging. Our batteries reduce the urgency of separate chargers which makes them best for modern lifestyles. Our rechargeable USB batteries are made to provide long-lasting energy and reduce the extra waste.

How Do Our Rechargeable USB Battery Work?
We use lithium-ion (Li-ion) inside our rechargeable USB batteries which brings high energy density and long life duration. Inside the battery a small, internal circuit goes through the charging and discharging process.
Then the circuit converts the 5V input from a standard USB port into the optimal voltage required to charge the internal Li-ion cell. For AA and AAA sizes, the internal circuit also brings the battery output to a constant 1.5V which is best for all types of DC devices.
Providing Rechargeable USB Batteries in Different Types & Sizes
Our Rechargeable USB batteries come in all types of styles and sizes which makes them compatible for most household DC devices.
AA and AAA Batteries
Our AA and AAA rechargeable batteries use lithium-ion (Li-ion) technology because a single Li-ion cell operates at a higher voltage (typically 3.7V), and provides a constant voltage of 1.5V. Which helps your devices at peak performance. The AA rechargeable batteries are used in wireless computers, high powered LED lights, electronic toys and remote controls. Whereas AAA batteries are used in remote controls, electronic toys and LED flashlights.
C Type Batteries
C type batteries are cylindrical in shape and they are larger in size than AA batteries and smaller than D type batteries and makes them best suited for the range of household devices that require more power than AA batteries but doesn’t require the massive capacity of a D cell.
The energy capacity of our C2 type rechargeable battery ranges from 3,000 to 5,000 mWh and features a USB port which takes 2-3 hours to take charge. C type batteries are used in musical equipment, remote controlled cars and portable radios.
D Type Batteries
D type batteries are larger than standard cylindrical battery types and provide a stable 1.5V output via internal voltage regulator. The capacity of the D Type batteries ranges from 6,300 to over 12,000 mWh and takes 4-7 hours to fully charge from the USB port. D Type batteries are used in heavy duty flashlights, outdoor lightings and motorized toys. For D Type batteries you can try our 9V rechargeable USB battery for other electronic devices.
9V Type Batteries
9V type batteries are rectangular in shape with two snap style terminals at the top that provide 1.5V constant voltage. Multiple Li-ion cells are connected inside the 9V batteries in the series to regulate the voltage output. The capacity of the 9V rechargeable battery ranges from 400mWh to over 650mWh. 9V type batteries are used in smoke detectors, walkie-talkie, guitars and multiple electronic measurement and testing devices.

Say goodbye to wasteful disposables and bulky chargers with our Rechargeable Batteries from NBS and stay powered.
Benefits of Our Rechargeable Batteries
Our rechargeable batteries come with a built-in USB port and provide constant voltage of 1.5V that prevents device performance from fading when the battery starts to drain. Also you can recharge multiple times instead of buying disposable batteries.
Instead of using alkaline batteries, rechargeable batteries are made from Li-ion tech which are less prone and protect your electronic devices.
Li-Ion Based Rechargeable Batteries for High Capacity
Our Lithium-ion batteries can store more energy in a smaller form factor as compared to the other older rechargeable batteries that makes it even more efficient for modern and compact devices. Also our high energy density batteries are helpful in renewable energy systems as they can be stored from solar panel systems in a relatively small footprint.

FAQ’s
Can I use rechargeable USB batteries in any device?
Yes, in most cases USB rechargeable AA, AAA, C, and D batteries made to work in any electronic devices that normally use those sizes.
Are rechargeable USB batteries safe to use?
Yes, our rechargeable batteries are very safe since most of the modern USB rechargeable batteries are made on the Li-ion technology and include a built-in Battery Management System (BMS).
How long do rechargeable USB batteries last?
The life of the rechargeable batteries are measured in “charge cycles” so it depends upon the usage that can last to several years.
Are they more cost-effective than disposable batteries?
Yes, rechargeable batteries are more cost effective than disposable batteries because you can recharge multiple times and can save up your cost.
Can USB rechargeable batteries be used in any device that takes regular AA batteries?
